Such a stunning place to visit, spend an hour or all day there – it’s all outdoors except the cafe. They often have events like basket weaving in kids holidays. It’s National Trust so you need to pay to go in.
In the winter they light up the abbey and have choirs and foodie trucks, you need to book.
